Application filed October 5, 1922.

To all 107mm t may concern Be it known that I, CAMILLE ANTOINE ZAoKInwioH, a citizen of the Republic of F rance, and residing at Paris, Seine Department No. 47, `Rue dl-autpoul, in the lll epublic of France, engineer, have invented certain new and useful Apparatus for the Control of the Leaves 'of lVeaving Looms, of which the following is. a specification.

My invention relates to an improved apy paratus for the control of the leaves of a weaving loom; wherein the. known jacquard pattern sheets are replaced by a set of revoluble discs (termed patterns) having disposed at the periphery one o-r .more teeth whose number and spacing are vc riable for the different discs. When rotating, the teeth of each pattern. disc. effect the momentary clutching of a. respective shaft with one or the other of two driving pinions mounted loose upon said shaft and in constant rotation in contrary sense; the consequentrotation of said shaft serve to raise ,or lower the corresponding loom leaf through the medium of adequate mechanical devices.

The present improvements chiefly relate to the devices controlled by said pattern discs and serving for the clutching of said leaf-controlling with the driving pinions. These arrangement-s principally comprise the use of an eccentric provided with a collar for actuating the forked levcrof each ciu-tch sleeve, said eccentric being so conn trolled that it rotates through one half revolution upon the passage of each too-th of the pattern. By these means, the apparatus is easy-running and it takes but a small amount of power.

A form of construction of an apparatus according to the invention is shown by way of example in the accompanying drawings.

Fig. 1 is a partial vertical section of the device, and,

Fig. 2 a horizontal section.

Figs. 8 and l are front and side elevational views, of a diagrammatic: nature, of the device as a whole and of the mechanical transmission for the control of the driving pinions and the patterns.

A description will first be given of the drive which relates to a single leaf of the loom.

A. disc, termed pattern, 1, carrying one orv Serial No. 592,609.

whose ratio is such that. disc 2 will turn through one half revolution at each passage of a tooth oit the pattern.

The eccentric disc/2 is mounted loose on a shaft 8 and rotates in a collar 9 connected by a rod 1() with a lever 11 pivoted to a stationary shaft 12; said lever actuates by a fork 13 a jaw clutch sleeve of double type let whichis slidable on a key upon the shaft 15.

By moving the lever 11 and sleeve 1st in one or the other sense, the clutch `iaws are actuated by the jaws of one or the other driving pinion 16, 17, which rotate loose-ly and in contr-ary sense on the. shaft 15; the latter is thus actuated in either sense and drives by means of a worm 18 and worm wheel 19 a pulley Q0 to which are secured the drawing bands 21 of one of the loom leaves. riseach tooth of the pattern passes along, it thus raises or lowers the corresponding strip. Jlifter the passage of the tooth, the eccentric disc as well as Ythe lever 11v and sleevelf/L occu 3y the inoperative position as indicated in tlie drawing, this position being maintained for example by a spring 22 slightly braking the pinion 4l, Fig. 1.

Each of the shafts 15 serving to actuate the looin leaves is "clutched in like mannerI by a corresponding sleeve operated by an eccentric, a set of gears and a respective pattern.

The apparatus set forth is intended for the control of 24 leaves, and comprises four rows of sii; shafts each, 15, and two rows of twelve patterns each, 1, for the control of the clutching of said shafts.

The pinions 16 which arc mounted on all the shafts 15 of a given row are in engagement in sequence, and the last pinion engages a pinion 23 disposed at the outside of the casing 24e of the apparatus. rlhe pinions 23 are connected togetherby pinions 25, and

one of them is rotated by a chain wheel 26 keyed to its shaft, said wheel being connected by `chain to a second like wheel mounted on the main shaft of the loom (not shown). In like manner the pinions 17 are in engagement, and the last one engages a. pinion 27. The various pinions 27 are ccnnected together by pinions 2S, and one of them is rotated in contrary sense to the respective pinion 23 by means of a set of bevel gears 29, 30. 31; the gear 29 is mounted on the shaft 32 the chain wheel 26; gear 30 is loose on a stationary axle, and gear 31 and pinion 37 are secured to the saine shaft.

The shafts 33 having lreyed thereto the pattern dislrs l, carry the pinions 34s which are connected together in pairs loy a pinion 35, and the latter is driven hy a Worin 36 Whose shaft 37' is connecte-d with the,driving shaft 32 through the medium of the bevel gears 3S, 39, d0, stl so that at each revolution of the main shaft, of the looin, the. patterns will turn through an angle equal to the pitch of their teeth.

The said driving mechanism as a Whole occupies hut a small spa/ce and can be inspected and lrept in order with facility.

Claims:

l. In an apparatus for the control of the leaves of a looni, the combination of a oontro'l shaft for each leaf, a clutch sleeve slidahle upon said shaft a forked lever engaging said sleeve, an eccentric disc loosely revoluble upon a stationary axle, an eccentric` Collar and an eccentric rod connecting said dise with said forked lever, a dise termed pattern having oneor more teeth and adapted to rota-te in coeoperation with the ina'in shaft of the loom, and vi'neans whereby said eccentric dise inay be turned through one-half revolution at the passage of each tooth of said pattern disc.

ing pinions loosely revoluhle. on one of the said shafts, clutch sleeves mounted on said shafts, a set of toothed dises termed patterns shafts having the, said patterns keyed thereto, means actuated hy the teeth of said discs and serving` to nieve the said sleeves, a driving shaft adapted to rotate in eo-op eration with the niain shaft of the looin, gear Wheels connectingv said shaft with one-half the said ilriving pinions mounted on the shafts, other gear wheels connecting said shaft with other drivingIr gear wheels Wherehy the latter shall he rotated in eontrai'y sense to the preceding, and gear wheels connecting the said driving shaft with the pat tern dise shaft. whereby each revolution of f the driving shaft shall cause the said patterns to move forward by a distance equal to the pitch spaing, substantially as described and iff-presented.

In test imony that I elaini the foregoing as niy invention, l have signed my naine.
